TPD is serving as the prime consultant for the preparation of alternatives analysis, preliminary engineering, and final design for the Bristol Road Extension project. Currently the project is at the end of preliminary engineering and will begin final design by June of 2026.  

The project is in the vicinity of Route 202 (Butler Avenue) and Route 152 in and around the Borough of Chalfont. This area currently experiences significant traffic congestion due to high traffic volumes that bottlenecks at Main Street downtown Chalfont. The Bristol Road project acts to alleviate traffic congestion and provide alternate routes for motorists and EMS by creating a new connection From Park Ave to Bulter Ave (parallel and north of Main Street) by extending Bristol Road. In order to further improve traffic mobility, improvements are also occurring at Main Street and Park Avenue, additionally a current all-way stop at Park Ave, Callowhill Rd, and Ferry Road will now be signalized. Main Street in Chalfont is currently a downtown area with many local businesses and driveways that are difficult to access and Main Street queueing at various intersections overlap during peak traffic times under existing conditions. Diverted traffic to Bristol Extension will also act to alleviate these issues as well.  

At this time alternatives analysis have been performed and the Bristol Road Extension concept was determined to be best approach in addition to other local improvements mentioned above. Significant public involvement was required to navigate the alternatives and preliminary engineering phases of the project. To date over 30 stakeholder meetings have been held, two in-person public meetings, and one public Teams meeting. An additional public meeting is also planned for the final design phase of this project. 

Along with significant public coordination this project involved complex traffic modeling which required development of an area-wide traffic study to determine the root causes of the congestion, compare alternatives, and to develop recommendations involving geometric and capacity adding improvements to the chosen alternative. Additionally, the intersection of Bristol and Butler need to be updated to add an additional leg to the intersection. Further complicating this process was an offset rail line crossing that required roadway alignment adjustments to center the rail line in the intersection, which required rigorous coordination with SEPTA.  The project also consider community features such as key local destinations and pedestrian networks.
